Description

A microcalorimeter with constant ambient temperature has been designed (approximately -1950C = temperature of the absorber), which could be utilized with doses from 10 rd upward. The G-value for ferrous sulfate was assessed by means of comparison measurements with the calorimeter and a Fricke-dosimeter, using two different electron energies. The G-value at 24.8 MeV amounted to 15.64 +- 0.14 ions/100 eV and at 38.8 MeV, to 15.60 +- 0.13 ions/100 eV. (orig.)

Abstract (German)

Es wurde ein Mikrokalorimeter mit konstanter Umgebungstemperatur (ca. -1950C Absorbertemperatur) konstruiert; es konnte bereits bei Dosen ab 10 rd eingesetzt werden. Durch Vergleichsmessungen mit dem Kalorimeter und Fricke-Dosimeter wurde der G-Wert fuer Eisen(II)sulfat bei zwei Elektronenenergien bestimmt. Der G-Wert bei 24,8 MeV betrug 15,64 +- 0,14 Ionen/100 eV und bei 38,8 MeV 15,60 +- 0,13 Ionen/100 eV. (orig.)
